Popping and Rattling in Your Cooling System

Popping and Rattling in Your Cooling System

noisesMy cooling system is still making noises that I don’t understand.  Should I be worried?  We have been on the topic of heating and cooling noises made by your HVAC system in St Louis MO near Afton for some time now.  And, we know that some are harmful and legitimately concerning while others can be dismissed.  “Popping sounds when you turn your system on and off you can breathe a sigh of relief.” The popping sound is due to your metal ductwork expanding and isn’t a problem whatsoever, according to your St Louis heating and cooling repair near Afton MO.  “For elimination of the sound, insulation such as foam or rubber can help limit the noise.”

There exist other sounds emitted by your Cooling system in St Louis that can be of greater concern, such as the thumping and clacking we discussed in a previous post.  When you hear such things, be sure to call your heating and cooling installation specialists near Afton for a complete HVAC work up.  Other sounds will be covered in posts to follow on behalf of your St Louis cooling installation and repair.  For now, let’s move onto rattling.  Rattling sounds usually indicate loose debris blowing around within your heating and cooling system in St Louis near Afton.  This, as harmless as it may seem, can be a big problem if left unchecked.  “Even something as small as a loose screw rattling about could lead to significant issues down the line. If the debris is larger in size, the rattling noise may sound more like a scraping noise, which is also not to be ignored.”

There is a level of DIY here, if you can pinpoint the location of the rattling, unscrew the vent and see if you can remove the debris. If not, contact a professional to locate and extract the debris as soon as possible, so as to protect your heating and cooling system in St Louis from potential permanent damage.

Natural Refrigerants

Natural Refrigerants

naturalNatural refrigerants are an unexplored subject in the cooling world. According to our recent research on behalf of your St Louis Cooling sales near O’Fallon, we have many reasons to further explore their impact on the environment and energy efficiency, as well as ozone damage, etc, based on compressor choices and options available in the cooling industry.

“While natural refrigerants are already a reality in commercial refrigeration, the home appliance industry has lagged behind in adoption.”  We have already explored oil free compressors, now the natural ones are up next for discussion. The United States has lagged behind Asia, Europe and Latin America in providing consumers with natural refrigerant options, according to our research on behalf of your St Louis Cooling Sales and Service near O’Fallon MO. “This is starting to change as end users, particularly in states with strict energy regulations and high levels of environmental awareness, are starting to demand natural refrigeration solutions.”

How does the EPA play a role here in the United States? “There is also increasing pressure from the Environmental Protection Agency (EPA) and the Department of Energy (DOE) on manufacturers to find refrigeration solutions that do not depend on fluorinated gases (F-gases).” Another encountered source, The Association of Home Appliance Manufacturers (AHAM), recently published an open letter announcing intentions to phase out the R134a refrigerant by 2024 while the EPA announced that a ban on this refrigerant could happen as early as 2021. R290 will be the natural refrigerant used in cooling with many compressors in St Louis MO near O’Fallon and it has zero ozone depletion potential so has much gain.

Oil Free Compressors Advantage

Oil Free Compressors Advantage

advantageThere exist a variety of subjects with cooling at the center.  Besides HVAC, Refrigeration is the next biggest related category and within that, we have much to research and discuss regarding compressors, more specifically still, the efficiency and ability of one compressor to the next in the St Louis Cooling Sales and Service near St Peters MO.  Oil free compressors are today’s focus.

Labeled as a breakthrough technology, oil free compressors are truly capable of revolutionizing residential refrigeration for the household market. According to facts gathered on behalf of your St Louis Cooling Repair near St Peters, “This technology, which has been available for households since 2014, expands the possibilities of appliance and kitchen design. Because it does not use oil, it is smaller and provides the manufacturer with more freedom in terms of where within the unit the compressor is installed.” This flexibility is a big factor in cooling since it not only provides appliance designers flexibility in how the equipment is configured but can also help save valuable real estate in the home kitchen where things already tend to be tight for many.

Cooing experts report that the home sector’s first oil-free compressor uses no oil due to a special surface coating and a single bearing lubricated by the refrigerant gas itself. Running on a wider range of capacity modulations instead of switching on and off, it is able to result in minimum temperature variation and better food preservation, according to all we read on behalf of your St Louis Cooling Sales near St Peters MO.  Described by professionals in the industry as compact, flexible, quiet, energy efficient and over 90% recyclable, the oil-free compressor is poised to transform home refrigeration without a doubt.

Alternate Cooling Dynamics

Alternate Cooling Dynamics

alternativeDid you know that when it comes to cooling a space, there exist many different means to an end?  “Dais Analytics in Florida, in partnership with Oak Ridge National Laboratory (ORNL), is developing a new membrane-based rooftop air conditioner, which would use water as a refrigerant instead of conventional chemicals.”  We are always seeking, according to the research recently done on behalf of your St Louis Cooling Sales near O’Fallon, ways in which to function sans chemicals. Not only is this technology perfect for sweltering, humid summer nights, but it could also save 30%-50% in electrical consumption compared to today’s roof top units, not to mention work to cut out the chemicals that we are always doing our best to avoid.

“United Technologies Research Center in Connecticut is exploring electrocaloric, solid-state technology to develop a heat pump that will keep a space cool without using any chemical refrigerants. This technology is ideal for residential and small commercial buildings.” It’s small and quiet, and could result in 25% system efficiency improvement, along with possessing fewer mechanical parts.  It is much improved in the Cooling Maintenance in St Louis near O’Fallon with the likelihood of increased reliability that results in a total reduction of your chances of losing A/C in the midst of a heat wave!

One of the other goals in this movement and wave of technology is based, according to our research done on behalf of your St Louis Cooling Sales and Service near O’Fallon is to develop an energy storage system that integrates with HVAC units to reduce the overall energy requirements of A/C systems by utilizing waste-heat that would otherwise be lost in traditional systems. Integrating ground-level diverse energy storage with HVAC could reach overall energy storage efficiency of 70% and improve HVAC performance by 35%.

Green Alternative Heating

Green Alternative Heating

greenWe spent the previous post discussing the measures that one randomly selected University was taking in the way of energy efficiency with green technology.  “Green heating and cooling systems fall under two distinct categories: passive and active.” Passive systems work by maximizing nature’s ability to heat and cool without furnaces or air conditioners [source: Green Technology]. “Among other things, passive technology includes constructing homes with white or light-colored roofs that reflect the sun’s energy instead of absorbing it.” As a result, the amount of energy it takes to cool a house is less. Passive designs also use windows that can keep the heat out and cool air in.  They remind me of staying safe from a sunburn by sitting in the shade as opposed to the chemical (active ways) of sunscreen.

According to our recent research on behalf of your St Louis Heating and Cooling near O’Fallon MO, active designs use a variety of mechanical heating and cooling systems. These systems tend to run on solar power, geothermal power or other sources of green energy.  It’s a gradual one, but the increase in green-energy use, according to your St. Louis Heating Sales near O’Fallon MO, in recent years is slowly having an impact.

“For one thing, Americans saved more than $19 billion in 2008 by using various green heating and cooling systems [source: U.S. Department of Energy].”  The cost is high, though, according to your St Louis Heating installation near O’Fallon. “But these green systems are not cheap — some solar collectors cost between $30 and $80 per square foot for installation.”  There are incentive programs offered now and then by the government, but not consistent enough to really go into details here.  The next several posts will cover all of the other green heating and cooling methods we uncovered.

Passive Cooling

Passive Cooling

passiveOn behalf of your St Louis Cooling Repair near South County MO, we are on a regular search for new information and research to pass along to you, in regards to green energy and cost effective, environmentally friendly ways to handle the heating and cooling of your home or business.

Along those lines, did you know that the sun is the ultimate provider of green energy?  A couple things that make it so are the constant and renewable nature of Solar power, the fact that it is not about to run out anytime soon.  There are, according to our research on behalf of your St Louis Cooling Installation near South County, ways in which you can benefit and enjoy the power of solar energy without the effects of direct sunlight.  “Passive solar energy is simple, has little to no moving parts and requires minimal upkeep. Passive solar-energy systems are designed to use natural principals of heat transfer instead of machines such as furnaces and air conditioners [source: Passive Solar Resources].”

It turns out, according to all that we read for your St Louis Cooling Sales and Service near South County, passive solar technology uses the building’s walls, windows and floors to collect, store and release the sun’s energy. “However, passive solar homes still need mechanical equipment, such as a forced-air system or radiant flooring to keep the temperatures cool in the summer and warm in the winter [source: Arizona Solar Center].” Direct gain systems are supposed to be the easiest of them all in terms of installation of cooling capable solar panels in St Louis MO.  In such systems, sunlight passes through windows where the light is converted into thermal energy. The walls and floors directly absorb and store the heat energy. As long as the room temperature is high, the interior of the homes will hold on to the heat. “When the temperature drops at night, the stored heat radiates through the living space.”

Induction Benefits in Your Restaurant

Induction Benefits in Your Restaurant

inductionIn the previous post here, on behalf of your Restaurant Equipment sales in St Louis, we covered the different ways in which you can cook in your commercial kitchen near Ladue.  One of the best methods of cooking when it comes to burner types is with an induction burner. Now, we want to talk about why this is the case.

Induction is more efficient.  “Because as much as 90 percent of energy used is turned into heat that cooks food, compared to less than 40 percent of gas and the 74 percent efficiency of traditional electric equipment, a commercial induction range is the most energy-efficient cooking equipment you can buy.”

Also true, and discovered in our research on behalf of your St Louis Commercial Restaurant Equipment sales near Ladue is the fact that induction cooking keeps your kitchen cool. “Because induction cookers generate heat only in the pan you’re cooking in, less ambient heat escapes into the air. Translation: your kitchen stays cooler than it would if you were using any other source of heat to cook with.”  Because of this fact about the heat distribution, induction cooking becomes safer to use as well, since the surface of the range stays relatively cool.  This is true even when it’s just been used to bring a stock pot to a boil.  Therefore, including induction cooling methods into your restaurant equipment in St Louis near Ladue, you will actually be keeping your kitchen staff safe from burns.

Also true of St Louis Restaurant Equipment near Ladue that includes induction capabilities is the following, “It offers quick response. Electronic controls let users make instant changes to pan heat levels. That precision control makes a commercial induction cooktop suitable for applications that require close control over temperatures like melting chocolate.”

Geothermal Heating and Cooling

Geothermal Heating and Cooling

geothermalWhen we are looking into different ways to cut costs both at home and in our commercial business, heating and cooling can be a great area of focus.  There are nonconventional ways to accomplish the heating and cooling that you are looking for that we researched completely on behalf of your Cooling installation in St Louis near Fairview Heights IL.

First recognize that the earth is brimming with a limitless source of energy – also known as geothermal.  The explanation of this begins deep inside our planet where you would find a lot of hot water and steam. The deeper you go, the hotter it gets, in fact. But you don’t have to dig too deep to take advantage of this energy, according to all that we read on behalf of your St Louis Cooling Sales near Fairview Heights IL. Only a few feet below the surface, actually, the temperature of the water remains constant year round, generally about 42 to 80 degrees Fahrenheit (5.56 to 26.67 Celsius) depending on where you live.  A geo-exchange system can use this energy to heat and cool almost any kind of building [source: Minnesota Geothermal Solutions].

Here is further explanation based on our recent research on behalf of your Cooling Service near Fairview Heights IL in St Louis MO.  “Geothermal systems do not directly tap into the heat inside the Earth. Instead, geothermal homes use heat pumps to take advantage of the constant temperature of geothermal wells under the ground. The heat pump can cool a house in the summer and warm it during the winter. Heat pumps have a fluid inside, which could be water or a refrigerant. When it is cold outside, the fluid absorbs Earth’s heat and brings it inside to warm the air.” In the summertime, the heat exchange works in reverse, cooling the house [source: APH Geothermal].

Beating the Heat With Proper Maintenance

Beating the Heat With Proper Maintenance

bright sunWhen summer is upon us, most people get excited and look forward to enjoying the summer sun and beating the heat in a cool, air-conditioned building.  The downside to this pleasure, according to all that we read on behalf of your Heating and Cooling in St Louis near University City, are the summer energy bills.  Most of us all know that the dog days of summer can mean high energy consumption at an unfortunately high price.

In fact, on behalf of your St Louis Heating and Cooling Sales near University City MO, we found a few stats to fill in the gap here and help illuminate the point.  “According to the U.S. Energy Information Administration, space cooling will consume an estimated 1.28 quadrillion British thermal units across the United States in 2017—that’s equivalent to almost 39 million homes’ electricity use in a year. And that energy use adds up.”

We also found, when reading various articles on behalf of your St Louis Heating and Cooling installation near University City, that in residential buildings, space cooling alone makes up 9% of a home’s total energy consumption.  There are also things that can lessen efficiency quite drastically.  “Additionally, typical air conditioning units use fluorocarbon refrigerants as a coolant, which, if leaked, can lessen the efficiency of an AC system and negatively impact the environment.” If you properly maintain your AC unit by contacting professionals, such as your St Louis Heating and Cooling Repair near University City, you will at least improve the chances of having a very efficient system.

 

Overheating Deaths

Overheating Deaths

fanLooking further into the effects of natural disasters on HVAC systems on behalf of your St Louis Heating and Cooling Repair near Clayton MO, we found some interesting information regarding the Great East Japan Earthquake and the tsunami that resulted in March of 2011.  “The aftermath of the Great East Japan Earthquake and resulting tsunami of 11 March 2011 provided researchers an unexpected opportunity to explore the relationship between air conditioning and risk of heat-related death.” According to our research on behalf of St Louis Heating Sales near Clayton, there have been many prior studies that reported associations between access to and/or use of air conditioning and lower mortality risk. However, the new results, published in Environmental Health Perspectives online, suggest that reducing the use of AC during summer heat may not necessarily have adverse consequences for human health, depending on the age and existing health of the people being considered.

The following was reported, “The 2011 earthquake and tsunami severely damaged the Fukushima Daiichi Nuclear Power Plant and caused severe electrical shortages in the Tokyo metropolitan area. To conserve energy, the government strongly encouraged residents served by Tokyo Electric Power Company and Tohoku Electric Power Company to reduce electricity consumption by 15% from July to September of 2011.

The urgency was heightened to reduce energy consumptions although campaigns promoting energy conservation have long been a summertime fixture in Japan.   Many residents of Japan working to reduce cooling bills and energy consumption swapped AC for fans.  The end results were not troubling to their health.  Interestingly enough, heat related deaths actually decreased during this time.
